Tuning the hysteresis loop for the anomalous Hall effect in Pt ultrathin films on by electrolyte gating
Leon Sakakibara, Yumiko Katayama, Tomohiro Koyama +2
Pt ultrathin films on ferromagnetic insulators have been widely studied for spintronics applications, and magnetic moments of interface Pt atoms were considered to be ferromagnetic…
Nonreciprocal magnon propagation in a noncentrosymmetric ferromagnet
Y. Iguchi, S. Uemura, K. Ueno +1
Relativistic spin-orbit interaction drastically modifies electronic band and endows emergent functionalities. One of the example is the Rashba effect. In noncentrosymmetric systems…
Electron carrier-mediated room temperature ferromagnetism in anatase (Ti,Co)O2
Tomoteru Fukumura, Yoshinori Yamada, Kazunori Ueno +7
Since the discovery of room temperature ferromagnetism in (Ti,Co)O2, the mechanism has been under discussion for a decade. Particularly, the central concern has been whether or not…
Ultrafast optical control of magnetization in EuO thin films
T. Makino, F. Liu, T. Yamasaki +6
All-optical pump-probe detection of magnetization precession has been performed for ferromagnetic EuO thin films at 10 K. We demonstrate that the circularly-polarized light can be…
Room Temperature Ferromagnetic Semiconductor Rutile Ti1-xCoxO2-δEpitaxial Thin Films Grown by Sputtering Method
Takashi Yamasaki, Tomoteru Fukumura, Masaki Nakano +2
Room temperature ferromagnetic semiconductor rutile Ti1-xCoxO2-δ(101) epitaxial thin films were grown on r-sapphire substrates by a dc sputtering method. Ferromagnetic magnetizatio…
Role of charge carriers for ferromagnetism in cobalt-doped rutile TiO2
T Fukumura, H Toyosaki, K Ueno +2
Electric and magnetic properties of a high temperature ferromagnetic oxide semiconductor, cobalt-doped rutile TiO2, are summarized. The cobalt-doped rutile TiO2 epitaxial thin film…
